Definitions

• the subject of the present invention is a nanostructural catalyst for the synthesis of gasolines, in particular via a low alcohol route, where water is a by-product, e.g.
• n and x in the above equation are dependent on the temperature and pressure in the system as well as the catalyst used in the process. This means that the catalyst, which, beside enabling the very synthesis reaction to occur, also influences the degree of the coupling process related to the degree of isomerisation of hydrocarbons to increase the octane number of the gasoline to be obtained. Also important is the catalyst's resistance to water present as a by-product of the synthesis.
• the objective of the present invention is to provide a novel catalyst formula for the synthesis of gasolines from methanol or its homologues, in particular its matrix, having high catalytic resistance to water, even above 100 ppm, that would also allow active sites to be appropriately deposited thereon for high and long-lasting activity of the catalyst and its selectivity towards increasing the degree of isomerisation of hydrocarbons in order to increase octane number of the gasoline to be obtained.
• the catalyst according to the present invention characterises in that its active sites in the form of copper ions are introduced in a coordinated octahedral structure and at a preferable amount of Cu in a range of 0,2 to 0,5 % by weight of the metal, by known methods, onto nanostructural aluminosilicate matrixes, in particular 10-channel matrixes of monoclinic crystal structure with channel dimensions from 7,6 A to 3,0 A, of high adsorptive capacity and ion exchange selectivity, thermal stability in the range 973 - 1023 K, and, preferably, Al 2 O 3 to SiO 2 molar ratio of max 10, and total surface area not greater than 40 m2/g, in particular in the form of ferrierite or clinoptilolite granules.
• Example 1 The present invention is illustrated by the following embodiments. Example 1.
• a catalyst named FERR-Cu was prepared, where as the matrix there were used 1,5 to 3 mm diameter granules of ferrierite, a hydrated aluminosilicate of sodium, potassium and magnesium in sodium form, of general formula (Na 5 K) 2 Mg[OHZAl 3 Si 15 O 36 ] • 9H 2 O, crystallised in a rhomboidal system in the form of needle-shaped crystals characterised by the following physicochemical data:
• a catalyst named KLIP-Cu was prepared, where as the matrix there was used clinoptylolite, a natural zeolite of identical chemical composition to that of ferrierite, crystallised in a monoclinical system (Cm symmetry group), in the form of granules of 1,5 to 3 mm in diameter, characterised by the following physicochemical data:
• the catalysts according to the present invention were subjected to evaluation in kinetic tests in ethanol coupling processes, assuming that an indicator of catalyst activity will be the reaction rate expressed as TOF (Turnover Frequency) towards the formation of ETBE (ethyl tert-butyl ether) as the most desirable product, as well as towards the formation of isomeres above C 5 hydrocarbons.
• TOF Treatment Frequency
• ETBE ethyl tert-butyl ether
